redline weber carb kits
 

hi and happy new year!!

I have a 71 250c and would like to hear from anyone who has successfully installed a REDLINE WEBER CONVERSION KIT# K245 on a 250 with m130 engine. of particular interest wound be :
a) DEGREE OF DIFFICULTY WITH LINKAGE
b) CHOKE ISSUES ,IF ANY
c) ANY AND ALL TIPS THAT CAN BE OF HELP IN MAKING THE CONVERSION

I will appreciate any and all comments you care to make.

thank you

I believe there are two basic kits, one by Redline and another by JAM Engineering. Both will do the job; I believe the Redline kit is slightly less expensive. Most commentary I have seem relates to the JAM kit. I understand the Redline kit uses some plastic parts whereas the JAM kit is all metal for the linkages, etc. I suspect there is little difference other than that and that may not be significant for a car that receives little use. If you expect to use the car heavily then the all metal JAM kit may be a better selection. The JAM kit was the subject of an installation article in the Mercedes Benz club magazine a few years ago. Check their website for a reference copy of that article. Neither conversion is a one-hour bolt on...you need to be a reasonably good mechanic with good basic skills.

I have the JAM kit in my 1970 250c. I bought the car with it so cannot comment on the installation. The fit, finish, and quality of components are all first class and I have not had any trouble with any of the JAM pieces. I recently bought rebuild kits from JAM and was happy with the service and information. I would suggest you give them a call.

I installed one for my '67 250S (dual progressive carbs). I was not thrilled with the instructions I got. The steps were out of order and some of the info was wrong ( I didn't get it from JAM ). Weber was good with support but I did have a problem with the linkage. On my kit, you have to retain parts of the old linkage. Also, the ends they send you are plastic. If you are taking them on and off (for adjustment) they can get loose. I would think that they could spend the extra dollar and get metal caps for a $900 kit. :mad:

If I were to do it again, I would buy (from Fastlane) the metal ends and not use what comes with the kit. I would also read the directions, read them again and then read them a third time. I would lay everything out and mentally go through all the steps. I eventually had to take the car to a mechanic (after a month of looking I found one who had my same car and wasn't intimidated by a carburetor) Tuning a dual carb is an art. It's working well now. I still have some choke "iffyness" but other than that it is MUCH better than the Zeniths I had. I don't care what anyone says, Zenith sucks.

I have a JAM kit on my 250C, and am very happy with it. Throttle tip in is good, and progressive throughout travel, chokes are electric, so no problems there....
