THE best way is to use a 1/8 NPT tap with a 11/32 drill bit. Thread in a 1/8 npt 1/4 barb fitting with threebond 1211 on the threads. I just blew an engine because the stock pulse fitting came loose on the case. REPLACE the other with a fitting while you are doing the 2nd.

The carbs can only flow what the needle and seat can let through right? I have 2 x 2.3mm dia N&S, which is 8.3mm^2 in flow area. It looks like my Y fitting is the smallest restriction in my setup with a diameter of 3.7mm which is a flow area of 10.75mm^2. I guess it could work, I should...

I was wondering if 46 buckshots on a 62t/61x would get enough fuel when running the reserve switch. I am at 1mm over, 185psi, type 4 dry pipe with water injection. I like the idea of the reserve switch, but dont want to lean it out. I would appreciate some opinions or better yet experience...

Just a tip for keeping the brushes back while sliding the armature into position. Use a pair of needle nose and gently twist the spring up and rest it on the upper outside edge of the metal frame that surrounds the brushes. The spring will rest here nicely, and the brushes will stay put. Then...

Good I am sick of getting raped.

You can move the stock bilge to the screw that is port of the stock location. Screw looks like it is holding the top and bottom of the hulls together. I just put my bracket in a vice to flatten out the 90deg bend in it.

You could smooth that out and use loctite bearing retainer to fill the gaps. That would likely be the last time the cases get split though.

Can you tap a 2nd outlet at the front of the head that goes right to an additional pisser? I have a single line to my exhaust manifold, one out the front of head to pisser, one out rear of head to drypipe. Seems to run well.

I think you are rich with the low jet, maybe closer to 105. Pop off seams low, maybe closer to 18-20.

I painted a 550 with perfection, I used Primekote first. Make sure to get the correct thinners I used 202 and 333. I rolled and tipped mine it looked great from a few feet, up close there was a bit of orange peel. You will need a quart kit of primer and paint.

8.5 volts is too low for the starter. You need 10-11volts for it to crank well, a drop from 12.4 or so to 10-11 is typical.

Maybe clean out the jets on the MAG side carb? sounds like that could be leaning out your mixture.

The best thing you can do for that 550 engine is put a 44 SBN on it.

I am looking for any info on this head I have. Made by a guy named Jari Heinonen in British Columbia.

If I can make a suggestion to make the search easier, setup an RSS feed reader. You will need a program to collect the data, I use netnewswire for osx. Go to craigslist for the area you want to search and search for superjet, then at the bottom of the page look for the RSS button. This is the...
