First, read your post...and immediately ordered the book "Super Tuning and Modifying Holley Carburetors by Dave Emanuel.
Second, while I'm waiting for it to arrive...I have a boat, Thunderbird Formula 180 (I/0) with a 1974 Mercruiser 188 (Ford 302), Holley 6317-1 (looks like a 4150), double barrel...
I'm far from an expert, but I'm all I've got.
- I rebuilt the carb.
- After the rebuild I had some trouble starting and keeping it running. (start-quit, start-quit)
- The float adjustment was too high, flooding and quiting. (my assessment)
- I adjusted the float (1/3 clockwise) and now it starts so so.
- No plastic or glass sight plug in this model, it's a screw.
- Was worried about pulling the site plug and spilling gas on running engine, so that's my Q below. Need some advice on the how to.
- Once running it idles smoothly.
- If I accelerate slowly, it runs fine from 800 RPM up to 2500+ and runs smoothly.
- If I accelerate quickly, under load, in the water, it stalls.
- Starts again easily.
- I don't think I had it stall with the muffs on accerating quickly, but that's a moot point I think, in the water counts.
I'm sure I need to complete adjustments and the instructions with the kit are not specific enough for a novice (assumes you know too much).
For example:
1. Do you remove the sight plug before or after starting?
2. Do you adjust the float height with the engine running?
Interested in your thoughts while I'm waiting for the book.
Thank you.
