Had a couple of goes writing this reply as the phone died.
Went back, and looked around for any air leaks that jump out to me, tightened up the bolt that clamps the carb to the elbow leading to the head, but only slightly.
Tried starting again, no luck.
So checked the bowl and dumped fuel out of there but no fuel came out, so undid the carb for the ?th time today to adjust the float, did this a few times until got fuel running out of the drain plug for the carb.
Then the better half came out, still didn’t start after multiple attempts.
Better half left, not encouraged by my progress.
So I thought about the air, and covered the air filter with my hand and it started. Revved up and then died as I took my hand off the airfilter. So I tried it again and left my hand on the filter for a while longer and low and behold back into life.
Took my hand off and as it started to die I half covered it and away it went.
I left it running for a bit on the jack and altered the throttle screw bringing the revs down a bit.
I left it running, revving it a little for a couple of minutes. I then stopped it and easily started it again with no hand on the filter. So got my daughter to have a go around the backyard and was able to restart it easily.
However I left it a couple of hours and it was back to being stubborn.
Not starting at all.
So I dumped the fuel from the carb, out it on prime briefly and then back to run, it would fire but not run
Eventually I put a rag over the air filter as couldn’t get my hand on it due to the plastics, stuffed it as tightly as I could and it started.....
It ran for a bit then died so I did the same again and away it went. I had no time to keep playing with it however getting an idea that blocking the airfilter to start it works until it’s warm, then once warm we are away.
I can’t put my finger on why it’s apparently working when starving the airfilter.
Does this allude to an air leak somewhere still?
Daughter loved it when it was going, the dog not so much, ohh well.
