It rained yesterday..did not work on the motor..today back at it..got new plugs.champion825...went to install the lower one and it would not start...just started to bite then popped back out...acted like it was stripped,Jardin to believe because it just unscrewed a little hard when I removed it ...after more investigstion...there is a helicoil in it...after trying a thread chaser which wouldn't start,I've removed the coil,will be looking for a tool and another one ...I expect to be back working on it on friday...everything is new it should run when I can get this last plug in..I'm thinking that it may have been losing ground compression because it was stripped it didn't help that that coil didn't work either..will keep you posted...thank you all for your suggestions
