Trouble with my engine

    Hi I pulled the cars out of the loft last week now the better weather is on its way back.
    Pulled the CEN CT4 and it started first time, ran it round the deck for a tank then put some after run oil in and put it away.
    Got the Thundertiger TSN4 out and tried that. It wouldnt start and I noticed that on some of my pulls there was no friction. After flooding the engin and loosening the glow plug off I got it started and it felt fine once it had warmed up.
    Do you know why sometimes the pull start wouldnt turn the engine over? Do you think it could be a lack of compression?

    If you had to tune it leaner (needle in further) to make it go right, than you used to tune it before, then the compression is down some.

    Is your fuel still fresh? It might not be your engine.

    Fuel is from last year so it will be degraded. This was like pulling fresh air, no friction from the motor but then on the next pull you could feel the motor turning over?

    Likely it is just a little clogging of the tubes from dried up fuel. If the engine didn't receive any juice on the 1st priming, there would have been little compression, and therefore easy to pull recoil starter.
    2nd time...a little juice gets through = compression = harder to pull, and engine fires.

    I will see how well it fires up at the weekend and let you know.

    take off your pull starter carefully and put some oil on the inside of the bearing where it meets the crankshaft.put it back together and it should work fine.
