engine problems!!!

[microfone90210]

just bought a savage xl. guy before me has put 4 tanks of fuel through it. was starting fine. put some fuel in today and it just wont start. took the engine out and took of the roto plate and everything seems ok. Problem is when i turn the shaft manually the engine seems to get stuck at a certain point. can anyone help?? thanks

If it's getting stuck, it sounds like it is still tight at TDC. Try loosening the glow plug a little before starting it to relieve some of the compression,or heat the block prior to starting it, but remember to re-tighten the plug once it's started. Also make sure your glow igniter is good and charged and that the glow plug itself is still good.

It needs to be leaned a little on the LSN and replace the Glow plug.

Hi, ive tried everything you guys said and i still cant get it started! it gets sooo close but just want start! anything else i can change? ive heated the block up which seems to help but when i tighten the spark plug it goes tight again(as in the roto start gets stuck). anything i can do?

[cuz]

roto-start fully charged?? On a fresh mill with a tight pinch roto's can have trouble cranking fast enough.

got it started now thanks to everyones help but after a few seconds...it varies the engine just stalls and shuts off any settings i can change? or anythign i can do thanks

Lean the LSN a little more, or you may need to increase the idle gap slightly. Don't idle it on a block, just get it started and runing with the wheels off the ground. That's the old school method of breakin. Get it warm, start it up and start driving easy in figure 8's varying the throttle. If it dies as soon as you try to acclerate, lean the HSN. Run it for a tank, shut it off, and let it cool for 30 minutes. Repat that a few times. You do not want the engine blubbering and bogging from being too rich. It wil not breakin correctly, more than likely it will snap the rod or piston. Try to keep it between 200 to260F while your driving it.
Fuel flow from idle to 1/4 throttle is controlled by the LSN. Make very small adjustments.
1/4 to full throttle the HSN takes over. Listen to the engine and lean it just enough to run clean when it is warm. allow a few minutes between adjustments. Do not do any top speed runs for the first 1/2 gallon. You can let it rev up, but let it go back to idle a few seconds. Constantly varying the throttle. After you finish the first gallon, then start to tune for performance. After all that, then you get to adjust the tranny if it needs it. Most do.
If at any point the rpms slowly rise at idle, you have leaned the LSN too far. Shut it off, let it cool down, richen it back up 1/4 turn and try again. Remember to keep the throttle trim set so the carb does not close further when you go from idle to brake position.

now im having more problems the rotostart gets stuck whenever the gp in tightened. with the gp is loose or off the engine will turn fine but as soon as i tighten the gp the engine jams and i cant start the car?? really stuck help please!!!

Keep the glow plug loose until it starts.

[microfone90210]

i didnt know i could do that
what could be causing it? just stiff engine?

Your engine is probably in better shape than it should be with 4 gallons on it. Which is great! Just make sure you tighten it back down as soon as it's running. Loosen it a half turn or so. You can use the ignitor to snug it right when it starts. Then use your plug wrench to tighten it properly. Just don't let the plug spin inside the ignitor. Not sure if it would damage the ignitor or not.

Could be hydrolocking.
Did you purge built up fuel from the engine before trying to restart it?
Remove the glow plug, turn the vehicle upside down and hold a rag over the cooling head. Using your rotostart turn the engine over it over a few times - like second or two.
If you have a build up of fuel, the rag will catch it.
Then put in a new glow plug and try to restart.
If there's no fuel, then you have one tight puppy of a mill and the other fixes mentioned above should get you on track.

One more thing, when you try to restart it, don't overprime the engine - which can lead to hydrolocking as well as damaging the OWB.
I stop the priming sequence as soon as the fuel reaches the intake nipple on the carb. Then turn everything on and and put the igniter on the glowplug and try to fire it up.
