08/07/16 - Major Progress on Bugsy there were show stoppers by myself got made today and I discovered some interesting things about Bugsy's engine. I got help from fellow Sprite Owner Tim Bosse today. Progress included:
1) Drum Brakes bled all around and readjusted, I now have a solid pedal and I'm not worried about stopping the first time I roll down my driveway. This car has all new brake hardware including new Master that was installed on the car. This will be replaced when I change out to front disks and later backing plates and wheel cylinders after driving season is over.
2) Emergency Brake now works and is correctly adjusted. Tim pointed out some doofus had totally loosened the E-Brake Tension rather than tightening it up. Gee I wonder who that doofus was, but I now have E-Brake that works correctly.
3) Clutch bled after a little help from my Mity Vac, Got on sale at Father's Day at HF, on sale for $29.95 less a 25%coupon. I managed to stand on my head and with one of the many gizmos that come with this kit a few pumps of the Mity-Vac and I was pulling fluid up and over the hump.
4) Old Bendix fuel pump that was mounted on the Front Fender removed and replumbed up front Ready to go on the engine side. New SU Fuel Pump is partially mounted, one Riv Nut Installed and the other will get completed tomorrow night, electrical is run to the rear bulkhead with a fuse. I need to get a two 1/4" tp 5/15" Barbs to connect the fuel lines to the pump and tank feed. Riv Nut Tools, you need the strength of Hercules in your hands to set a 5/16" Riv Nut. Glad I went down to the Hardware Store and get a 23/64 Drill Bit instead of just going with a 3/8" Bit. I 64' less I needed to compress that Riv-Nut. Fuel Pump almost ready to go maybe 1-2 hours work and "fettling" and it will be done,
5) Verified that I do indeed have Spark - A good thing, now whether I have it at the right time remains to be seen but I do have Spark. Once fuel Pump is ready, double checking timing will be next. We did try a little bit of Starting Fluid and I was gratified to hear at least one or two pops.
Now the Fun Stuff.
- Clue 1 - Bugsy has a really nice long twin pipe header. the two pipes join 12-18" after the pipe goes through the floor. It is a larger diameter than a BE Standard Exhaust Pipe.
- Clue 2 - Tim commented, nice to see Bugsy has HS-2 on it rather than HS-1's. Now I'm thinking someone has worked on this engine. There is a claim that it was rebuilt that I can't validate but the engine number plate is missing which happens when It has been hot tanked.
= Clue 3 - Pulled the Valve Cover off. What head is under there . Hmmm Casting says 12A185, WTH is that mean.
Valve Intake
Diameter 1.4 in
Valve Exhaust Diameter 1-5/32 in
Chamber volume 21.4 cc
Used on all Cooper S engines other than MG1300, 1300GT and last S's
Those are the same Valve Sizes as a 1275 uses
Holy Crap - Don't know for sure as some 12A185's came with smaller valves but guessing after seeing the HS-2's and the Header I may have something here. These heads were prone to cracking but if there is any kind of decent cam in this engine this engine could be a whole lot of fun to be had in a few days. Guessing it's set up for top end work. Anyone got any idea what kind of power this setup might make? Guessing it's more than 43 HP.
Another question, the header on this car. Do 948s, 1098's, and 1275's all use the same header? in other words could this header and exhaust work on my 1275?
Anyway work continues. Getting closer to having Bugsy IV on the road. Wheels go back on tomorrow and Bugsy will be getting off of jack stands before next weekend.
