Some of you will know about my 200 build as you you've helped me A LOT. As I move farther into driving my car daily again I have another problem...
Originally, I had a rebuilt HW 5200 direct mounted to my log head and I was having problems with it seeping fuel when I shut the engine off. I rejetted this carb with the jets that the jeep guys are using on their 258ci-6(found in the weber sticky). I had nothing but problems with this carb from the start and screwing the air/fuel screw all the way in would not make it stumble, let alone die... It ran extremely lean(plugs were chalk white) with the recommended 258 jets in it so I started looking for another carb thinking this one was messed up internally....
Kid down the road blew up a 258 in his jeep and sold me the weber 32/36 that was on it for $30. I used one of his adapter plates from his jeep to make the linkage clear and have it bolted up now. It runs much much better than the HW 5200 that was on it but I don't know what jets are in the weber, neither does he.
All readings listed below were taken at relatively same air temp today in Ohio (80*) on same drive. I drove for about 10-15 minutes at each speed to let the water temp level off and hold. The thermostat is new and is a 195* thermostat.
Idle(30 minutes)--195*F
50mph--190*F
60mph--195*F
70mph--200*F
I tried to hold the throttle as close to steady as possible and I set the timing before the drive to 10*BTDC at roughly 600rpm with vacuum to DUI disconnected and plugged. I do not have access to a Tach. right now so guessing 600rpm is the best I've to offer. The vac line on the DUI is manifold vacuum and the engine does not ping when the engine is wound out. The tank was half a gallon from empty and i filled up with 94 octane before this drive.
My best guess is as I'm approaching speeds of 60-70mph, I'm right at the boarder of opening up the secondary and I'm getting lean condition which is raising the water temp. I'm worried because I think it should be getting cooler as the air speeds increase, but it seems lean to me.
Should I stop stressing about the water temp that is 10-15* higher than I would like it to be??? I have a Holley 2300 that a buddy gave me, I want to change to it but it will require more time and tinkering to get the car running again.
I have to drive the falcon the rest of this week on the freeway and I am being worked in Cincinnati next week which means I need to be able to drive my car 100 miles to Cinci and then drive 50 miles everyday next week for work. Any thoughts on how I can get this water temp down, or what is causing it???? One of my friends said that it could run just a smidge warmer because the engine is so fresh but nothing drastic.
Thanks,
Stephen
