RICK IN VERMONT 12-30-2012 07:54:11 71.161.192.143 Report to Moderator	1954 SC - rebuilt the engine. It was running when I parked it. I had the head checked at local engine machine shop, all o.k. they put new guides in, nothing else. I installed new rings & bearings, nothing else, now it won't start. Not getting gas at the carb. when turning over there is a "tink-tink" noise coming from exhaust. Timing is perfect. Haven't tested compression but it appears to be o.k. Any thoughts?

Set your valves at .017" cold. Nothing else means you should've installed a new sleeve kit that included new pistons and rings. That ting you hear is probably a piston ring hitting the ridge in your old sleeves. Hal   [Reply]  [No Email]

Strainer in carb inlet clean? float stuck? That should get fuel if looked into. Before going into the fuel and trying to start it, there are basic and important realities that need attention. There is a ridge that is formed where the top ring stops moving on the way up. That ridge is almost always big enough to break a new ring that is placed in contact with the ridge. Standard procedure is to machine that ridge out of the cylinder, then hone the bore and then put in new rings (they will make their own new ridge as the tractor is operated for 7000 hours). If the ridge was ignored that "tink" sound is desperate (or broken) rings. As noted below, there is no way to provide a reasonable valve seal with new guides and no re-seating of the valves to the seats. They never line up and maybe 3 of 8 would be functional. Cold setting of the valve lash is also not mentioned in your post. With the changes made, the lash will certainly be way off. Tell us more, we want to see this thing run and run well.

Valves have been set. Cylinder walls were deglazed and the grooves in pistons were all cleaned before new rings installed. The guy at the machine shop said the valves all looked good and there were no cracks so he only replaced the guides???   [Reply]  [No Email]

Does it develop vacuum? Pull the hose off the carb inlet and put your hand over it while cranking. You should feel it suck.   [Reply]  [No Email]

Hasler, 12-30-2012 08:48:48   With the air cleaner hose off try to start it but as you do hold your hand over the carb air intake. You should both feel a good suction there and also when you remove your hand it should be covered with gas. If you do not have both then your compression is to low as in no suction or if no gas your carb is clogged some place. Note if you do that it also might try to start. If low suction put say a table spoon of ATF/gas mix in each cylinder and try to start it. The ATF/gas mix 50/50 will up compression and also burn like gas and may end your problems   [Reply]  [No Email]

I would bet valve timing or clearance if you are hearing noises in exhaust. Check the clearances again.   [Reply]  [No Email]
