18hp intek fouling plug and slow to turn over on start

[Bonose]

First post so be gentle.

Have craftsman lt2000 with Intek 18hp single cyl. I have 2 problems with it. One is difficulty turning over on start. Battery is good so i think its the relay. I have tapped the side wall where relay is bolted and it seems to get it to connect better. Can this relay (think thats what it is) be rebuilt or cleaned up to give correct starting or does it need to be replaced?

Next problem is fouling of plugs. After 10hrs the plug is black and oily and has to be cleaned and the engine uses notable amounts of oil. I have adjusted valves, were pretty good anyway. Thinking rings or valve guides. Dont have compression check yet. Suggestions for rebuilding the top end? Any youtube videos or instructions you recommend?

Thx

Absolutely, remove negative post from battery & tuck away for SAFETY. Remove relay & clean rust, corrosion, etc. with wire brush, be sure to wear safety glasses. Reinstall relay & give it a try, relays can be replaced not rebuilt, not expensive. As far as engine goes need information, all numbers from engine data plate, how old is tractor & engine, what year, & how many hours on hour meter if you have one on dash? Also post model & serial numbers from under seat, thanks.

An 18 hp single cylinder Intek is most likely a 31 series which need the valves adjusted periodically to keep the compression release working efficiently. I think you have two problems, Valves needing adjusted (OR bad camshaft) plus blown head gasket.

I can send you a Service Manual for your engine and or detailed Instructions for setting your Valves plus it has a check for compression release failure IF you like. Address below, put in proper format, remind me engine model number and what you want.
