Re: Engine trouble
i guess you have not turned the engine over by hand (ratchet on crank pulley nut) with the rocker cover removed prior to starting the engine. you should do that to check for any contact before starting the enigne. now that you know which guide is causing the problem you can inspect it during use using this method. it sounds like the guide has not been pushed in fully. i would rip it out and check it is not damaged at the end, and check for any deposits or bits of crap where the end sits.
