That will cause problems for sure. Someone left it off not thinking it was important probably.
Get rid of the "decompression system". The oil viscosity has nothing to do with your problem.I try with and with out the choke. and The compression is good 70 psi because of decompression system and no smoke.
I will try new oil 10W30 I like Castrol brand. Ho, the Coil module is new also.
Well, that's crap....Continental aircraft engines minimum equates to 40 psi by differential test. 70 is fine for a decompression released engine.70 PSI is barely enough to support combustion, but it has a compression relief so that should really not be an issue.
New coil? As in Amazon? I avoid Amazon due to the many problems I've had over the years.
Vapor lock....One thing that comes to mind is fuel percolation in the fuel bowl after shutdown. All that post-shutdown engine heat directly effects the carburetor.
Years ago, we had to look around at similar models to find an insulator/ heat shield that mounted with the muffler, but extended down to protect the carburetor from heat absorption,
This heat shield greatly reduced the percolation problems and improved the hard start when hot problems.
I looked on Ebay and they show a couple of different used ones for the Tecumseh HM100. Maybe one will be a good fit for your engine.
Hope this info helps you,

How can you compare a Continental aircraft engine to this design? They are totally different.Well, that's crap....Continental aircraft engines minimum equates to 40 psi by differential test. 70 is fine for a decompression released engine.
I can and I did. Multi cylinder vs single is not such a stretch. Both will be down on power and the single more so but it will run at 70. Saying it won't isn't true.How can you compare a Continental aircraft engine to this design? They are totally different.
