The Powermaster gear reduction starter you are installing is a very good starter. It's nothing like the old Powermaster "Vintage Torque"you are removing. Good choice.
I think it could work well. Keeping it under the hood sides might be a challenge but may be possible. Certainly will flow enough for most any Model A,even modified engines. Interesting thought.
100+ ft lbs to rotate is far too tight to take a chance. If the cylinders are rusty the new rings are not going to be happy even if you soak them. If the bearings are that tight it will destroy itself on startup if you try to force things. It needs to have the pan removed to check bearings and...
If a man wants to resurrect an old tired block and is willing to pay for the work, there's no reason a machine shop should refuse the work in my opinion. Yes, I do work at such a shop and yes we'd do the job as long as it's possible with the condition of the block in question. (No horrible...
So is compression ratio and weight of the rotating parts like a lightened flywheel. The throttle linkage ratio of an A is also a factor...it's a pretty quick ratio thus the need for the foot rest next to the throttle.
If strictly thinking about the carb, then yes venturi size and air speed...
The way a multi vis oil works is when cold it behaves like the lower number (like a cold 85) and as it warms up the additive package keeps it from thinning as much so it ends up behaving like a ("hot" 140) when fully warm. It's an attempt at keeping the viscosity level over the operating temp...
If the clutch disc is rusted to the flywheel the flywheel still turns but the clutch will not release and the transmission input shaft is spinning and won't allow you to shift...just grinds. By far the most common problem after sitting undriven for a while,especially in damp weather or...
This is good advice and matches your symptoms. Check each valve spring to make sure none are broken and that they "feel" the same when pried open with a lever. An intake at .008" clearance shouldn't cause your misfire.
