My first impression/experience - This is a solid product. If I had some tee's I could make up a four carb unit but I probably won't, I like the simplicity of this one.1. Even rechecking both sides it was much quicker and easier than ever before. I just adjusted until the fluid quit changing elevation side to side. Just for kicks I checked the left side and right side again and they were still right on. I did the left side carbs, then the right side carbs and then the rear left and front right to balance sides. Filled it with water containing red food coloring. I used the hoses from the SyncPro with the orifices in them, a meter stick, some clear tubing and some tye-wraps. I guess the o-rings aren't sealing on the needle valves anymore. Today I set it up, reluctantly, and it kept sucking air into the tubes. Every time I finished a sync I wondered why I bothered because I had no faith in what I did. Big mistake, I have struggled endlessly with this thing, won't repeat calibration, air separation in the blue fluid and a very busy fluid level. When I bought the SyncPro, five years aga, my thoughts were to build a manometer, but no, I decided to buy the "right" tool for the job. Old thread I know, but I found it while trying to sync my carbs with my SyncPro which is always a pain in the butt. I want to take the opportunity to thank Goose for being so generous with his time, talent, and coffee. I don't think the pluses outweigh the minuses, and I am not convinced it will do the job. In short, I don't think I can recommend the SyncPro. What's worrying is that you lose the calibration when you blip the throttle (change the vacuum). And that's the vacuum you sync to, give or take. I think it was because you calibrate at idle, which gives you a given vacuum. So, why did the SyncPro work as well as it did? Looking at Goose's vacuum pump test, you would think it shouldn't. Maybe if I hadn't reversed hoses, I could have gotten nearly decent results. When Goose got L/R together, the RPMs surged like crazy. I had problems getting L/R to come together, and it turned out that while not horrible, they weren't that close either. 1 & 2 were sync'd OK, and 3 & 4 were sync'd OK, but left & right were not sync'd together properly. Well, he disliked the SyncPro before I left Houston, but how did it do? As I admitted earlier, I bungled the repairs to it, so I expected the sync to be off. It would seem that blipping the carb would send the SyncPro out of calibration.įor fun, I am including a photo of Goose's tool. When he returned it to 5 inHg, it was out of calibration and fragmented too. The second shows that it goes out of calibration at 10 inHg, and is clearly wacked at 15 inHg. The first shows the SyncPro calibrated at 5 inHg.
Goose hooked it up to a hand-held vacuum pump. But it was reputed to work, so he wanted to see how well it did. To be sure, there is much to dislike about it. Goose was determined to prove the SyncPro to be junk. Goose did not like it on reputation, and liked it less on sight. First it was the roofing screw, then it was meeting lobo17 (he came to see the carb work), but one of the more interesting surprises was how the SyncPro "works".
I bought the SyncPro and took it with me when I visited V7Goose yesterday for carb work.
#MOTIONPRO CARB SYNC FLUID PRO#
We've talked a lot about the SyncPro ('Carbtune versus Motion Pro SyncPro' and 'Carbtune/SyncPro vs 4 seperate vacuum guages' being two recent conversations).
