Well to tell you the story, i started by taking the foam out of the air filter and putting some filter oil onto it, i turned on the transmitter and reciever to check that it was all working correctly, it turned out the trim for the steering was out a lot, the wheels were turned sharply to the left, but i fixed it, the steering was also in reverse, but i changed it at the flick of a switch. I also checked the opening of the carb, and that seemed to be fine. So i took out the glow plug and checked it, then dropped a few drops of oil into the engine, i placed the glow plug back in and gave the pull start a few pulls to lube up the parts
With the prep finished i took the car outside to the park and filled up the tank with fuel, i put my finger over the exhaust and pulled to attempt to prime the engine but i couldn't see much going on in the pipe (It was difficult however as the rascal has a rubber exhaust that tends to bend around as you put your finger over it) so i took the pipe off the exhaust and blew into it which worked much better! I placed the glow start in and began to pull on the pull start, but little happened. After about 15 or so pulls i decided to up the throttle trim slightly, but still i got nothing, so i upped it more, till i decided it was reaching a dangerous level, then i pondered for a second
I knew that the glow plug was working, i had checked, the fuel was in and primed so i knew that wasn't a problem, the idle was not too low, it was now open quite a bit, so it couldn't be that. I assumed it was something to do with the pressure of the fuel line - possibly the tank was poorly sealed, or that the engine was too cold.
So, hoping that it was just too cold, i took the car back to my house and used a hair dryer to get it nice and warm. I took the car out to my drive, put the glow in and within a few pulls it sprang into life. I took the glow out and gave it a gentle rev, it cut. I started the engine back again, and this time remembered that i should give it a few revs with the stick in, and so i did, it lasted for about 2 seconds before it cut again. I checked through the manual and it said that if it stalls when you accelerate the LSN could be too lean, so i richened it a 1/12 of a turn, but it seemed to make it worse as i could not get the car to start. Confused, i decided that i would double check the settings of the needles, and so i used the factory basics from the manual which was HSN: 2 and a half turns screwed out from the furthest in, LSN:0.70mm in from flush (Practically flush), and the idle i knew was fine already. I said a quick prayer lol and then i tried it again, and it worked! The engine ran and i let it idle for a second before i plucked up the courage to give it a slight rev, thinking it would stall. But it didn't, it seemed to be working fine
I ran it around my drive in a figure of 8 for about 3 minutes, then i cut it off and let it cool down at BDC, the temp i checked was around 220F, which seemed good. I let it cool down for about 5 minutes before i started it again, and just as before it worked fine, it started within a few pulls and then it drove with no stalls. I repeated the process and let it cool down.
The major trouble came when i went to start it again, it was a bit tougher to start, and i was pulling away (Short, sharp pulls, not fully extending the string) when all of a sudden the string came out of the pull start >.< It was frayed slightly at the end so i can only assume it had slowly been wearing away, not sure if it was my fault or if it had been maybe a slightly dodgy pull start. I was disheartened, because it was a bad end to it all, things seemed to be going well but that kinda put a dampener on things
But anyway, i have ordered another pullstart now, just hoping that it will start when i next get it fixed >.< (And that it will be easy to change)
Just thought i would share my story with you guys as i have posted quite a few things about how to get my engine run in and i wanted to let you know how it went ^^
